You will Need:1)Pencil, Highlighters, Calculator2)Density – 2 pages 4 sides –

Picked up yesterday

1) Binder Check #2 – Due Thur. Oct. 17th at the beginning of class

2) Test #2 – Thur. Oct. 17th- Target Concepts on-line- ½ page of notes front side only done by hand

3) Density – Due on Friday – Oct. 18th

1) Name any of the methods for finding volume.

2) What three unit labels for volume are equivalent.

3) If I know the volume and the density of a substance, how do I find the mass?

4) What vocabulary word describes when CO2(s) changes to CO2(g)?

5) What is the density formula?

6) Separating the salt from salt water is a physical change. What vocabulary word describes how I would do this?

7) Why is photosynthesis a chemical change?

8) Physical or Chemical: Deposition of gas to ice.

9) The dependent variable in an experiment would be displayed on which axis on a graph?

10) CO2(s) + energy CO 2(g) :

chemical or physical?

11) Which Law states that matter cannot be created or destroyed, just rearranged?

12) What kind of changes do not result in the production of new substances?

13) Give verbs that describe a chemical change.

14) If I give you a “golden” coin, how could you find out if it was real gold?

15) A direct relationship between the independent and dependent variable would produce a graph that looked like?

1) Identify which number values you have by looking at the unit label (mass, volume or density?)

Mass UNIT GRAM or any form of gram…kg, cg, mg

Volume UNIT mL, cc, cm3, m3

L

Density UNIT Combination unitg/mL, g/cc, g/cm3

mass volume

2) Place each number into their correct place in the triangle.

Volume Number

Mass Number

Density Number

3. If you have a top and bottom variable in the triangle – DIVIDE (numerator by denominator) to find the missing variable.

If you have the two variables on the bottom – MULTIPLY them to find the top variable.

Volume Number

Mass Number

Density Number

divide

multiply

1. Complete all the problems by showing your work.

2. Hint: If the problem is worth more than 5 points you may have to:

1) Solve for Volume First, then Solve for Density

2) Answer a question as well

1. Binder Check #2 – Due Thursday at the beginning of class

2. Test #2 – ½ page of notes due Thursday. Front side only, done by hand

3. Density – 2 pages 4 sides – Due Friday at the beginning of class.
